In San Patricio, with vehicle traffic relatively low, dust from nearby fields and occasional burning are the bigger day-to-day factors. Tree cover is sparse in the immediate area, so this particulate load moves through largely unimpeded. Day-to-day readings still shift with wind direction, traffic volume, and weather conditions. Local monitoring for the wider area tends to track closely with this general pattern.

Is air quality bad in San Patricio right now?
On 30 August 2026, overall air quality in San Patricio is poor. AQI is the main air quality indicator at 70.7/100. Pollution peaks around 6:00 PM (PM10: 70.7/100).
Will air quality be worse tomorrow in San Patricio?
On 31 August 2026, air quality conditions in San Patricio will be better than today, with AQI forecast at moderate at 55.2/100. Pollution peaks around 12:00 AM (PM10: 55.2/100).
When is air pollution at its worst in San Patricio?
From December to February, average wind speeds run around 15 km/h with temperatures near 15°C, calm and cool enough to let particulate matter and smoke build up near the ground rather than disperse. From July to September, temperatures average around 30°C, warm enough for strong sun and heat to drive ground-level ozone formation.
Are air quality levels in San Patricio based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
